The following defines an RPC service that is also served over HTTP via grpc-gateway. Standard response codes for both are defined here: https://github.com/grpc-ecosystem/grpc-gateway/blob/master/runtime/errors.go

AdminService service methods

Method Name	Request Type	Response Type	Description
CreateTask	TaskCreateRequest	TaskCreateResponse	Create and upload a Task definition
GetTask	ObjectGetRequest	Task	Fetch a Task definition.

ListWorkflows	ResourceListRequest	WorkflowList	Fetch a list of Workflow definitions.
CreateLaunchPlan	LaunchPlanCreateRequest	LaunchPlanCreateResponse	Create and upload a LaunchPlan definition

CreateExecution	ExecutionCreateRequest	ExecutionCreateResponse	Triggers the creation of a Execution
RelaunchExecution	ExecutionRelaunchRequest	ExecutionCreateResponse	Triggers the creation of an identical Execution
RecoverExecution	ExecutionRecoverRequest	ExecutionCreateResponse	Recreates a previously-run workflow execution that will only start executing from the last known failure point. In Recover mode, users cannot change any input parameters or update the version of the execution. This is extremely useful to recover from system errors and byzantine faults like - Loss of K8s cluster, bugs in platform or instability, machine failures, downstream system failures (downstream services), or simply to recover executions that failed because of retry exhaustion and should complete if tried again. See ExecutionRecoverRequest for more details.

GetNodeExecutionData	NodeExecutionGetDataRequest	NodeExecutionGetDataResponse	Fetches input and output data for a NodeExecution.
RegisterProject	ProjectRegisterRequest	ProjectRegisterResponse	Registers a Project with the Flyte deployment.
UpdateProject	Project	ProjectUpdateResponse	Updates an existing Project flyteidl.admin.Project should be passed but the domains property should be empty; it will be ignored in the handler as domains cannot be updated via this API.
